iGE=CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 326,827, datedSeptember 22, 1883.

(No mod cl To all whom, it nmy concern:

Be it known that we, JOHN P. ANDERSON and Jiioon 0. KELLER, bothcitizens of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Ice-Cream Freezers, which improvement is fully set forthin the following specification and accompanying drawings, in which-Figure 1 represents a central vertical section of an ice-cream freezerembodying our invention. Figure 2 represents a top or plan View of aportion thereof.

Similar letters of reference indicate corresponding parts in the twofigures.

Our invention consists of an ice-cream freezer in which the can and thedasher or beater may be rotated independently of each other, and thedasher or beater either rotated or rendered inoperative, as desired, forthe purpose of ice-cream making.

Referring to the drawings, A represents a tab, which is provided with astep, a, and B represents a rotatable can, which is placed within saidtub and supported on the step a thereof.

G represents the dashcr or beater of the freezer, the shaft D of whichis supported on astep within the can B, and passes freely through thetop of the same and through a miter-wheel, E, which is secured to saidtop. Meshing with the wheel E is a miterwhcel, F, to which power iscommunicated in any suitable manner, said w ieel F, in the present case,being secured to a shaft, G, whose bearings are on the frame H of thedevice.

The shaft D is divided, the two sections be ing connected by a coupling,J, within which is a key, K, which is fitted to said coupling andengages with grooves on the two sections of the shaft, so that saidsections may move as one, and the upper section and the coupling beraised when desired.

The upper section, D. of the shaft D passes through a rising and fallingsleeve, L, which is located in the boss M of the frame H, said bosshaving a recess, b, to receive a .lug, N, which projects from the sleeveL,

whereby the latter is prevented from rotation, it being seen that thesection D of the shaft D is rotated within the sleeve L, and held inposition therein by means of a washer, c, which is secured to saidsection by a screw, (1, and rests freely on the upper edge of the sleeveL.

Keyed or otherwise secured to the upper section, D, of the shalt isamiter-wheel, P. which, as is evident, rises and falls with said sectionand the sleeve L.

Depending from the upper arm of the frame H, adjacent to the boss M, isa pin, Q, which is so disposed that when the wheel P is raised it entersan opening in the latter and prevents rotation of the same.

In order to hold the wheel P, sleeve L, and section D in elevatedposition, we employ a pin, R, which is inserted in the boss M, so as tohave the lug N bear against the same, as most clearly shown in Fig. 1.

It will be seen that when the parts are in position shown in Fig. 1 thewheel P is raised from the wheel F, consequently, when power is appliedto the shaft, and as the wheels F E are engaged, rotary motion isimparted to the can B, the cream or mixture to be frozen being placed inthe latter. The dasher or beater G, however, remains inactive orstationary, owing to the coupling J, section D of the shaft D, andmiter-wheel P being held by the pin Q, it being noticed that the can Band miter-wheel E rotate on the lower section of the shaft.

\Vhen it is desired to rotate the dasher or beater, the pin R iswithdrawn from the boss M, whereby the wheel P is lowered clear of thepin Q and engaged by the wheel 1*, the sleeve L also lowering, and withit the shaftsection D, the lower end of the latter moving into thecoupling J, and as the wheel P is rotated power is communicated to thesection D, and owing to the key or feather connection of the coupling Jwith said section D, and also the lower section. D, of the shaft D, thelatter is rotated, the direction of rotation being the reverse of thatof the can, the latter receiving its motion from the wheel E through themedium of the wheel E, as hercinbefore stated.

\Vhen the wheel P is in its engaged or lowermost position, it isprevented from rising by insertion of the pin B through the boss M intoan opening in the lug N of the sleeve L. The wheel P may be again raisedas desired, thus throwing the dasher or beater out of gear and renderingthe same inoperative, and adapting the can to be rotated independent ofthe dasher or beater.

In order to relieve the key K of strain, we employ screws f, which-arepassed through the coupling J and tightened against the two sections D Dof the shaft D, either when the section D is raised or lowered, theupper bolt being loosened during the operation of raising or loweringthe upper section, D.

When the can is to be removed, the coupling J is raised clear of the topof the lower section of the shaft D, the can with its connected partsthen being readily withdrawn from the tub.

We do not claim, broadly, as new a clutch I mechanism connecting thebeater and can,

neither do we claim a rising and falling beater, for such are old.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. A can, a beater, and a divided beatershaft, in combination with theboss M, formed with a recess, 12, a rising and falling sleeve, a risingand falling gear-wheel, the rising and a falling section-of saidbeater-shaft, a feathered coupling for the divided shaft, and gearingfor the can, said sleeve having a lug which enters the recess b,substantially as and for the purpose set forth.

2. A can, a beater, gearing for the can, a divided beater-shaf i, asleeve, a boss, and a gear-wheel, in combination with the pins Q R,substantially as and for the purpose set forth.

3. A can, in combination with a divided beater-shaft, gearing connectingsaid can and beater-shaft, a frame, a boss attached to said frame, anadjustable sleeve working within said boss and secured to the upperportion of said beater-shaft, and a pin or lug attached to said frameand adapted to be inserted in a wheel secured to the said upper portionof the beater-shaft, substantially as and for the purpose set forth.

4. Acan, in combination with a beater, a divided beatenshaft, afeather-coupling for against the sections of said shaft, a sleeveforming the bearings for the upper section of the divided shaft, andagear-wheel connected with said section, substantially as and for thepurpose set forth.
